TECHNICAL FIELD

[0001] The present invention relates to moving pin archery sights havinga sight pin mounted to a sight in mechanical connection with a sight pinpositioning mechanism that includes a positioning mechanism framesecurable to an archery bow, a sight holder slide that is movable upwardand downward along a predefined vertical trackway of the positioningmechanism frame, a pivoting, sight holder slide positioning armpivotally connected at a pivot point to the positioning mechanism frameand mechanically linked along a slide connecting end portion thereof tothe sight holder slide such that, as a user adjustment end of thepivoting sight holder slide positioning arm moves along an arcuate pathin a substantially first direction, the sight holder slide moves along astraight path in a second direction substantially opposite the firstdirection, the pivot point being between the user adjustment end and theslide connecting end portion; the sight being carried on the sightholding slide; each angular position of the user adjustment end of thepivoting sight holder slide positioning arm indicating a differentdistance to a target such that a user may adjust the position of thesight pin of the sight to correspond with a particular distance to atarget by moving the user adjustment end of the pivoting sight holderslide positioning arm to the particular angular position correspondingwith the particular distance to the target; and more particularly to amoving pin archery sight that includes a ratio adjustment mechanism forallowing a user to varying the ratio of movement between the useradjustment end of the sight holder slide positioning arm and the sightholder slide to mechanically compensate the moving pin archery sight foruse with particular arrow speeds generated by particular bow and arrowcombinations and/or different arrows with the same bow and/or a distanceto target indicator/selector mechanism that allows a user to select adistance to target that corresponds with a predicted distance to atarget.

BACKGROUND ART

[0002] Moving pin archery sights allow the archer to move the sight pinto compensate for the distance to the target so that once the distanceto the target is selected, the archer sights in on the target in thesame manner by aligning an eyehole on the bow string, the tip of thesight pin and the target. Although moving pin archery sights allow forthe repositioning of the sight pin to compensate the sight for the arrowdrop expected for the distance to the target, they often do notaccurately compensate the sight because the mechanical movement of thesight pin is calibrated for the flight of an arrow moving at aparticular calibration arrow speed. Thus, if the arrow being shot fromthe bow is moving at an actual arrow speed that is either faster orslower than the calibration arrow speed, the arrow will hit the targeteither too high or too low, respectively. It would be desirable,therefore, to have a moving pin archery sight that included a ratioadjustment mechanism for allowing a user to varying the ratio ofmovement between the user adjustment end of the sight holder slidepositioning arm and the sight holder slide to mechanically compensatethe moving pin archery sight for use with particular arrow speedsgenerated by particular bow and arrow combinations and/or differentarrows with the same bow. In addition, because the archer mustmechanically adjust the sight to position of the sight pin for aparticular distance to the target, it is often difficult for an archerwho does not know what the distance to the target will be until rightbefore the arrow is to be shot, such as while bow hunting, to adjust thesight without missing the chance for a shot at the prey. It would be abenefit, therefore, to have a moving pin bow sight that included adistance to target indicator/selector mechanism that could be rapidlyadjusted to the desired target distance. Because the prey could escapewhen the archer averts his/her eyes to make the distance adjustment tothe moving pin sight, it would be a further benefit to have a moving pinsight with a distance to target indicator/selector mechanism thatemitted a slight, audible click for each increment of distance to beadjusted for so that the hunter could maintain his sight pin on the preyas the adjustment is made and release the arrow immediately after orwhile the distance correction is made should the prey begin to moveaway. Because hunting situations differ and the prey may be withinshooting distance over various distance to target ranges, it would be afurther benefit to have a distance to target indicator/selectormechanism which included multiple adjustment increment sets so that thehunter could select the increment set that most closely matched thecurrent hunting conditions.

EXEMPLARY MODE FOR CARRYING OUT THE INVENTION

[0023] FIGS. 1-8 and 3A illustrate various aspects of an exemplaryembodiment of the improved moving pin archery sight of the presentinvention, generally designated 10. Improved moving pin archery sight 10includes a sight pin 12 mounted to a sight, generally designated 14 inmechanical connection with a sight pin positioning mechanism, generallydesignated 16, that includes a positioning mechanism frame, generallydesignated 18, securable to an archery bow 20 with screws 22; a sightholder slide, generally designated 24, that is movable upward anddownward along a predefined vertical trackway 26 of positioningmechanism frame 16; a pivoting, sight holder slide positioning arm,generally designated 28, pivotally connected at a pivot point 30 topositioning mechanism frame with a pivot screw 32 and mechanicallylinked along a slide connecting end portion thereof, generallydesignated 34, to sight holder slide 24 such that, as a user adjustmentend, generally designated 36, of pivoting sight holder slide positioningarm 28 moves along an arcuate path in a substantially first direction“A”, sight holder slide 24 moves along a straight path “B” in a seconddirection substantially opposite the first direction “A”. Pivot point 30lies between user adjustment end 36 and slide connecting end portion 34.Sight 14 is carried on sight holding slide 24 and is attached theretowith two screws 40.

[0024] According to the mechanical construction of moving pin sight 10,each angular position of user adjustment end 36 of pivoting sight holderslide positioning arm 28 indicates a different distance to a target suchthat a user may adjust the position of sight pin 12 of sight 14 tocorrespond with a particular distance to a target by moving useradjustment end 36 of pivoting sight holder slide positioning arm 28 tothe particular angular position corresponding with the particulardistance to the target.

[0025] In this embodiment, the improvements to moving pin sight 10include the addition of a ratio adjustment mechanism, generallydesignated 50, and a distance to target indicator/selector, generallydesignated 52. Ratio adjustment mechanism 50 is provided for allowing auser to varying the ratio of movement between user adjustment end 36 ofsight holder slide positioning arm 28 and sight holder slide 24 tomechanically compensate the moving pin archery sight 10 for use withparticular arrow speeds generated by particular bow and arrowcombinations and/or different arrows with the same bow. Distance totarget indicator/selector mechanism 52 is provides the user with threeuser selectable sets of adjustment increments and also allows the userto verify that the distance to target setting has been adjusted bothvisually and audibly by counting the audible clicks generated by thedistance to target indicator/selector mechanism 52 as the useradjustment end 36 of the sight holder slide positioning arm 28 movedfrom a known distance to target location to the desired distance totarget location.

[0026] In this exemplary embodiment ratio adjustment mechanism 50includes a slide bushing, generally designated 56; a slide bushingpositioning assembly, generally designated 58; a bushing position marker60; and a set of arrow speed indicator markings, generally designated62. Slide bushing 56 has a first bushing end 64 slidably entrapped alonga slide bushing trackway 68 of sight holder slide 24 that is oriented ata ninety degree angle to the straight path of travel 26 of sight holderslide 24 and a second bushing end 70 threaded onto a positioning screw72 of slide bushing positioning assembly 58 that is rotatable by a userby grasping and turning a connected adjustment knob 74 to positionbushing marker 60 at the desired setting indicated with respect to theset of arrow speed indicator markings 62. Slide bushing positioningassembly 58 is mounted to slide connecting end portion 34 of sightholder slide positioning arm 28 and is operable to allow the user tovary the position of second bushing end 64 along slide connecting endportion 34 of sight holder slide positioning arm 28 and is configured tohold second bushing end 64 at the user set position with respect toslide connecting end portion 34 until positioning screw 72 is rotated bythe user. Bushing position marker 60 rides on slide bushing 56 in amanner to change position along with the second bushing end 70 in afixed 1 to 1 ratio. The set of arrow speed indicator markings 62 areformed onto a surface of slide connecting end portion 34 adjacent tobushing position marker 60 and parallel to the line of travel ofposition marker 60 along positioning screw 72 such that the user mayposition the bushing position marker 60 adjacent to a particular speedindicator marking 81 to calibrate the ratio of movement between the useradjustment end 36 of sight holder slide positioning arm 28 and sightholder slide 24 to the arrow speed at which a particular arrow, shotfrom the archery bow 20 to which moving pin sight 10 is attached, leavesthe archery bow 20. The set of arrow speed indicator markings 62indicate higher arrow speeds closer to the pivot point of sight holderslide positioning arm 28. The distance between pairs of individual arrowspeed indicator markings 81 become incrementally larger as the arrowspeed indicated by the individual arrow speed indicator markings 81incrementally decreases. In this embodiment, the distance between thearrow speed indicator mark 81 for an arrow speed of 330 ft/sec and thearrow speed indicator mark 81 for an arrow speed of 330 ft/sec is about0.15″; the distance between the arrow speed indicator mark 81 for anarrow speed of 300 ft/sec and the arrow speed indicator mark 81 for anarrow speed of 270 ft/sec is about 0.18″; the distance between the arrowspeed indicator mark 81 for an arrow speed of 270 ft/sec and the arrowspeed indicator mark 81 for an arrow speed of 240 ft/sec is about 0.28″;and the distance between the arrow speed indicator mark 81 for an arrowspeed of 240 ft/sec and the arrow speed indicator mark 81 for an arrowspeed of 220 ft/sec is about 0.39″. This varying distance between arrowspeed indicators occurs because at a level trajectory, (disregardingother variables such as wind direction and speed, the physicalcharacteristics of the arrow head and flights of the arrow, and similarconsiderations), the arrow drops a distance “D” during the time it is inflight that is proportional to the square of the flight time between therelease of the arrow and when it strikes the target. The distance “D” iscalculated classically by the equation D=at² where “a” is theacceleration caused by gravity or 32 ft/s² and t is the flight time. Theparticular distances between particular pairs of arrow speed indicatormarks 81 is also a function of the physical size of the sight 10 and thevarious physical mechanical interrelationships between the parts of theparticular sight pin positioning mechanism of a particular moving pinsight to which the improvements of the present invention are adapted.

[0027] The moving pin sight 10 may be calibrated for a particular arrowspeed using bow 20 and a particular arrow by adjusting the position ofthe bushing position marker 60 until the shot arrows are hitting thetarget at two predetermined distances. The two furthest distances thatcan be shot by the archer will yield the most accurate setting of thebushing position marker 60 and the most accurate arrow speed calibrationof sight 10 for a particular arrow and bow. The archer can then read thearrow speed adjacent to the bushing position marker 60 from the set ofarrow speed indicator markings 62.

[0028] The pin sight 10 may also be calibrated for a particular arrowspeed using the conversion tables of FIGS. 6,7 and 8. When the sight 10is to be calibrated with the conversion tables, the archer shouldmeasure from the target out to 60 yards on a near level surface and makemarks every five yards. The speed indicator should then be set to 300ft/sec and the distance to target indicator/selector 52 positioned atthe 20 yard position. The archer should then shoot arrows at the targetfrom the twenty yard mark and adjust only the sight 14 using a verticalsight adjustment 120 provided on sight 14 to raise or lower the tip end124 of sight pin 12 until the archer consistently hits the target at theaimed target spot. Do not move the distance to target indicator/selector52 from the 20 yard position until this adjustment is made.

[0029] The archer should then move the distance to targetindicator/selector 52 to the 60 yard mark (or the farthest of the 50 and40 yard marks if the archer cannot shoot accurately from 60 yards). Thearcher should then move to the 60 yard spot (or the respective 50 or 40yard spot) and shoot arrows at the target moving toward or away from thetarget until the archer consistently hits the targeted spot. The archershould then measure the spot from which he/she is shooting accurately,look up the spot distance on the appropriate conversion chart and readoff the arrow speed positioned next to the spot distance. The archershould then calibrate the sight by positioning the bushing positionmarker 60 adjacent to the arrow speed indicator marking 81 thatcorresponds with the arrow speed read off the conversion chart.

[0030] In this embodiment, the distance to target indicator/selectormechanism 52 includes multiple sets, generally designated 84 a, 84 b, 84c, of oblong, curved-sided, seating structure cavities 86 formed into apivoting sight holder slide positioning arm facing surface 88 ofpositioning mechanism frame 18 and an oblong, curve-sided, matingstructure 90 extending outwardly from a positioning mechanism framefacing surface 92 of a mating structure member 94 that is carried on theuser adjustment end 36 of pivoting sight holder slide positioning arm28. In this embodiment, oblong, curved-sided, seating structure cavities86 are molded into a molded plastic insert 87 secured into acorrespondingly shaped cavity 98 of positioning mechanism frame 18 andheld in place with screws 100. Mating structure member 94 is also moldedfrom plastic. Oblong, curve sided, mating structure 90 is shaped andsized to at least partially seat into and releasably engage each of theoblong curved sided, seating structure cavities 86 provided in thisembodiment.

[0031] Mating structure member 94 is moveably positionable and securablein each of three securing positions 108 a,108 b,108 c that are selectedsuch that, when mating structure member 94 is secured in one of thethree securing positions 108 a,108 b,108 c, the oblong, curve sided,mating structure 90 moves over and is engageable with a correspondingset 84 a,84 b,84 c, of oblong, curved-sided, seating structure cavities86. The gap distances between the seating structure cavities 86 of set84 a are equivalent to one unit of distance, (such as a yard or ameter); the gap distances between the seating structure cavities 86 ofset 84 b are equivalent to five of the same units of distance used byset 84 a; and the gap distances between the seating structure cavities86 of set 84 c are equivalent to ten of the same units of distance usedby set 84 a. The relative sizes and orientations of the user adjustmentend 36 of pivoting sight holder slide positioning arm 28, the oblong,curved-sided, seating structure cavities 86, the surface of the moldedplastic insert 87, and the oblong, curve sided, mating structure 90 areselected such that the mating structure 90 is moveable between separateseating structure cavities 86 by two methods.

[0032] In the first method, the user moves the mating structure 90between separate seating structure cavities 86 by pushing useradjustment end 36 of pivoting sight holder slide positioning arm 28 in adirection away from the surface of the molded plastic insert 87, and theoblong, curved-sided, seating structure cavity 86 being moved away fromuntil mating structure 90 is free to move over the surface of the moldedplastic insert 87 without contacting. The user then positions matingstructure 90 over the desired the selected seating structure cavity 86by pivoting user adjustment end 36 of pivoting sight holder slidepositioning arm 28 while it is still deflected. Pivoting user adjustmentend 36 of pivoting sight holder slide positioning arm 28 is thenreleased and mating structure 90 engages the selected seating structurecavity 86.

[0033] In the second method, the user simply pushes user adjustment end36 of pivoting sight holder slide positioning arm 28 in the directiontoward the desired seating structure cavity, because the sides of boththe mating structure 90 and the seating structure cavities 86 arecurved, pushing on user adjustment end 36 of pivoting sight holder slidepositioning arm 28 in the manner described causes the curved surfaces ofthe mating structure 90 and the particular seating structure cavity 86with which it is currently engaged act against each other to deflect theuser adjustment end 36 of pivoting sight holder slide positioning arm 28sufficiently to allow mating structure 90 to disengage from theparticular seating structure cavity 86 with which it is currentlyengaged slide over the surface of plastic molded insert 87 and then snapinto the adjacent seating structure cavity 86 in a manner that generatesa slightly audible click sound. In this manner the archer can move themating structure 90 from engagement with a known particular seatingstructure cavity 86 to a desired selected seating structure cavity 86 byknowing which set 84 a,84 b,84 c, of oblong, curved-sided, seatingstructure cavities 86 is being used and by counting the audible clicksuntil the desired seating structure cavity 86 is reached. This secondmethod allows the archer to maintain his/her sight pin on the prey ortarget and release the arrow immediately after the adjustment is made orduring the adjustment if the prey begins to move out of range.

[0034] It can be seen from the preceding description that an improvedmoving pin archery sight has been provided.

[0035] It is noted that the embodiment of the improved moving pinarchery sight described herein in detail for exemplary purposes is ofcourse subject to many different variations in structure, design,application and methodology. Because many varying and differentembodiments may be made within the scope of the inventive concept(s)herein taught, and because many modifications may be made in theembodiment herein detailed in accordance with the descriptiverequirements of the law, it is to be understood that the details hereinare to be interpreted as illustrative and not in a limiting sense.

What is claimed is:
 1. In a moving pin archery sights having a sight pinmounted to a sight in mechanical connection with a sight pin positioningmechanism that includes a positioning mechanism frame securable to anarchery bow, a sight holder slide that is movable upward and downwardalong a predefined vertical trackway of the positioning mechanism frame,a pivoting, sight holder slide positioning arm pivotally connected at apivot point to the positioning mechanism frame and mechanically linkedalong a slide connecting end portion thereof to the sight holder slidesuch that, as a user adjustment end of the pivoting sight holder slidepositioning arm moves along an arcuate path in a substantially firstdirection, the sight holder slide moves along a straight path in asecond direction substantially opposite the first direction, the pivotpoint being between the user adjustment end and the slide connecting endportion; the sight being carried on the sight holding slide; eachangular position of the user adjustment end of the pivoting sight holderslide positioning arm indicating a different distance to a target suchthat a user may adjust the position of the sight pin of the sight tocorrespond with a particular distance to a target by moving the useradjustment end of the pivoting sight holder slide positioning arm to theparticular angular position corresponding with the particular distanceto the target; the improvement comprising: a distance to targetindicator/selector mechanism for allowing a user to select a distance totarget that corresponds with a predicted distance to a target; thedistance to target indicator/selector mechanism includes a soundgenerating mechanism that generates a sound audible to the archer foreach increment of distance adjustment made to the sight.
